ypupdated, rpc.ypupdated - server for changing NIS information
The Network Information Service (NIS) was formerly known as Yellow
Pages (yp). Although the name has changed, the functionality of the
service remains the same.
ypupdated is a daemon that updates information in the Network
Information Service (NIS) databases. It is activated at system
startup when the NIS_MASTER_SERVER variable is set to 1 in
/etc/rc.config.d/namesvrs file on the NIS master server. ypupdated
consults the file updaters in the directory /var/yp to determine which
NIS maps should be updated and how to change them.
By default, the daemon requires the most secure method of
authentication available to it, either DES (secure) or UNIX (without
ypupdated supports the following options:
-i Accept RPC calls with the insecure AUTH_UNIX credentials.
This allows programmatic updating of the NIS maps in all
-s Accept only calls authenticated using the secure RPC
mechanism (AUTH_DES authentication). This disables
programmatic updating of the NIS maps unless the network
supports these calls.
ypupdated was developed by Sun Microsystems, Inc.
